NEW BRUNSWICK — Molly Wei will continue her testimony today in the state's case against Dharun Ravi, a former Rutgers student who faces invasion of privacy charges for spying on his roommate last September.

Wei faced invasion of privacy charges but entered a pre-trial probationary program. If she completes the program, the charges will be dropped. In return, she agreed to undergo counseling, complete community service and testify against Ravi.

Monday afternoon, Wei told jurors that she was in her dorm room on Sept. 19, 2010 when she invited Ravi, who lived across the hall in Davidson Hall, to come over.

Ravi told her that his roommate, Tyler Clementi, had asked to use their room that night. He wanted to know what was going on in his room, so they turned on Ravi's webcam from Wei's computer, she said.

They saw a few seconds of Clementi kissing another man, and shut it off, she said.

Cross-examination of Wei will continue this morning. Prosecutors are also expected to call a Rutgers Resident Assistant who interacted with Clementi when he requested a room change.

Ravi faces charges of bias intimidation, invasion of privacy and hindering apprehension. If convicted on the most serious bias intimidation charges, meaning he targeted Clementi because he was gay, he faces up to 10 years in prison.

Prosecutors say that Ravi intentionally enabled the webcam to embarrass and intimidate Clementi.

Ravi's lawyer contends that Ravi wanted to see what was going on in his room because Clementi's guest was older and looked untrustworthy, and Ravi had expensive computer equipment in the room.

Clementi committed suicide a few days after the webcam incident, sparking national headlines on anti-gay bullying. Ravi is not charged in connection with Clementi's death.

The trial began on Friday and is expected to last three to four weeks. Prosecutors are also expected to call Clementi's guest in the dorm room that night, identified only as M.B., to testify.
